Engineering Contradiction Analysis
1Measurement precision
If users determine control parameters before inputting the combinatorial optimization problem, then the solving process can be executed, but users cannot adjust parameters in real-time to maximize accuracy
Solution Approach 1:
The system displays the current state of the solving process (energy function value, temperature, iteration count) in real-time, providing feedback to users about the optimization progress. This enables users to monitor the solving state and make informed decisions about whether to continue or suspend the process, effectively allowing real-time control based on observed performance.
Solution Approach 2:
The system transitions from a static parameter setup (where all parameters are fixed before execution) to a dynamic control model where users can suspend and resume the solving process multiple times. This dynamic approach allows users to adjust control parameters between suspensions, maximizing solution accuracy while maintaining operational flexibility.
2Productivity
If users execute the solving process without real-time monitoring, then the process runs automatically, but users cannot determine when to suspend or continue for optimal results
Solution Approach 1:
The system provides continuous feedback by displaying the solving process state (energy function value, temperature, iteration count) at regular intervals or when users request updates. This information feedback enables users to make informed decisions about suspending or continuing the process, preventing loss of critical solving state information.
Solution Approach 2:
The system introduces an intermediary control mechanism between the automatic solving process and user decisions. Users can suspend the process to review current state information and resume when ready, acting as an intermediary step that preserves both automated efficiency and user control without requiring constant manual intervention.
3Measurement precision
If users continuously monitor the solving process, then they can make timely adjustments, but the system complexity increases
Solution Approach 1:
Instead of requiring continuous monitoring, the system implements partial monitoring where users can check the solving state at predetermined intervals or trigger updates based on specific conditions (e.g., energy function improvement thresholds). This partial action approach maintains solution accuracy while avoiding the complexity of constant real-time monitoring.
Solution Approach 2:
The solving process is segmented into manageable execution units that can be suspended and resumed. Each segment maintains its state information, allowing users to review progress at segment boundaries without requiring the system to maintain complex continuous monitoring infrastructure. This segmentation simplifies the control mechanism while enabling accurate decision-making.
